This is possibly news.....though not necessarily. But at least it's random......and just barely battery related enough. My 300x was the victim of a savage crash......(cause undetermined).....(pilot error suspected).....in which a few of its delicate and complex sub-systems were rendered non-functional......some terminally, although fortunately replaceable.....like the upper main-shaft bolt system which was severely traumatized.....among others.

In spite of serious bludgeoning impact...the turnigy nanotech 45C 1300mah 3S lipo battery came through seemingly blessed with merely a dinged corner opposite where the wires protrude. Not sure if anyone else would notice anything wrong with it......yet I have it on "watch" status, just to be cautious. It still balances real nice.
